The old freeware MXI 4.3 is linked AC(1) - however during initialization
determines if it is indeed running in such a way that it can invoke APF
authorised services. For batch mode, the only requirement is that it is running
from an APF authorised library - for ISPF and REXX it also has further checks
to make (e.g. is MXITSF in AUTHTSF?)
If MXI 4.3 determines that it is running authorised then it enables certain
functions that would otherwise be disabled (cross-memory functions, certain
displays that depend on supervisor/non-key8 invocation).
You can still download the last genlevel MXI 4.3 from www.cbttape.org
Please be aware that MXI 4.3 has been frozen and is not being developed or
enhanced anymore. As new levels of z/OS and hardware are released certain
displays are beginning to have problems or not work at all - e.g. the DASD
display on z/OS 1.10 does not handle EAV volumes at all well.
MXI 4.3 has been replaced by a commerical product called MXI Generation II (or
MXI G2 for short).
If you are using MXI in anything other that hobbyist/curiosity mode, I would
suggest that you consider replacing MXI 4.3 with MXI G2 as this is the only
version of MXI that supports things like 64-bit, EAV DASD, PAV, zIIPs and zAAPs.

Do any listers have any knowledge of downsides to running the free MXI
authorised? By default it runs unauthorised.
If it runs without authorization, why bother to run it authorized?
Principle of least access should apply, I would think.
By authorized, do you mean APF authorized? As in, linked AC=1 and in an APF
library? Or do you mean something else, like some sort of RACF authorization?
